Material Examined. Holotype: CHINA: Yunnan: Gaoligong Shan, Nujiang Prefecture : Gongshan Co., Danzhu He drainage, 15.7-16.0 airkm SW of Gongshan, 27.622- 7°N, 98.587- 92°E, 2900-3100 m, 30 June-5 July 2000, H.-M. Yan, D. Kavanaugh, C.E. Griswold, H.-B. Liang, D. Ubick, & D.-Z. Dong (CASENT 9029313, HNU), 1 ♀.

Paratypes: [same data as holotype] (CASENT 9016254, CAS), 3 ♀ ; [same data as holotype] (CASENT 9029314, HNU), 2 ♀ ; Fugong Co., Lishadi , 8-9 km W of Shibali, 27.20055°N, 98.71399°E, 3221 m, 8 August 2005, webs on rocky cliff, night collecting along the road, forest, P. Paquin, D. Kavanaugh, PP-2805 (CASENT 9022506, HNU), 1 ♀ .

Etymology. Formed from the Chinese words for metal (jīn) and dragon (lóng

), referring to the element and animal of the Chinese zodiac when the holotype was first collected.

Diagnosis. Distinguished from M. changouzi by having the scape thicker basally than distally (Fig. 18D), from M. goudao by the presence of a scape (absent in M. goudao ; Fig. 29F ), from other Chinese Mysmena by the much longer distal part curved posteriorly and dorsally (Fig. 18D; compare to Figs 25F , 30A ).

Description. Carapace pale yellow, darker in head region. Sternum medium brown. Legs pale yellow, darker distally. Femoral spots on legs I and II. Abdomen dark gray with series of white patches dorsally and pair of unjoined longitudinal white lines laterally; posterior tubercle absent (Fig. 15F-H).

Vulva: Epigynum a scape, base soft and wrinkled, projects ventrally, distal tip curves posteriorly (Fig. 18D). Sclerotized portion of spermatheca/copulatory duct complexes separated by nearly twice their width (Fig. 21C). Fertilization ducts arise from posterior part of spermathecae, curve mesally.

Female (CASENT 9016254): Total length 1.38, carapace 0.37 long, 0.38 wide, clypeus 0.07, sternum 0.26 long, 0.26 wide, coxa IV separated by 1.79 times their width. Macrosetae: Leg I: patella d1, tibia d1; Leg II: patella d1, tibia d1; Leg III: patella d1, tibia d1; Leg IV: patella d1, tibia d1. Metatarsal trichobothria: TmI: 0.33; TmII: 0.32; TmIII: 0.39. Leg measurements: see Appendix A.

Male unknown.
